ABSTRACT:
A reel assembly includes a bracket and a reel pivotally received in the bracket. The bracket has a slanted face formed on a top face of the sidewall to be adjacent to the cutout for facilitating receiving of the extensions in the cutouts. A supporting arm is formed on a side face of the sidewall and has two steps formed on a top face of the supporting arm to increase load capability of the supporting arm. An inclined edge and an arcuate corner are formed on an inner face defining the through hole so that when a strip is extended through the through hole, friction to the strip by the inner face defining the through hole is reduced.
